Shelly Plus Uni

The Shelly Plus Uni requires a voltage range of 110-230V AC for operation. It is essential to ensure that the wiring complies with European electrical standards, including the use of appropriate gauge wire for the amperage limits. The unit must be wired with a neutral wire for proper functionality. Additionally, ensure that the installation depth meets the dimensions specified in the product manual for safe and effective mounting.

The Shelly Plus Uni can be easily integrated with Home Assistant using MQTT or REST API. To set up, ensure that the device is connected to your local network and configure the MQTT broker settings in both the Shelly app and Home Assistant configuration. This allows for real-time status updates and control from the Home Assistant interface.

The Shelly Plus Uni is commonly used for automating various electrical devices such as lights, fans, and appliances. Typical scenarios include controlling lighting systems, monitoring power usage, or integrating with existing smart home systems for enhanced automation. Its dry contact feature allows it to be used in a variety of applications including gate automation or alarm systems.

First, check the power supply to ensure that the unit is receiving the correct voltage (110-230V AC). Verify the wiring connections, particularly the neutral wire. If the device is still unresponsive, attempt a factory reset by following the procedure outlined in the manual. Lastly, ensure that your Wi-Fi network is functioning properly and that the device is within range of the router.

The Shelly Plus Uni is a universal relay that offers dry contact capabilities, making it distinct from other devices like the Shelly Plus 1 or 2, which are primarily designed for controlling single or dual loads directly. The Uni is ideal for scenarios where a relay is needed to integrate with existing systems, while the others are designed for direct control of electrical devices.
